Abstract
A package opener (10) includes first and second opposed elongate members joined together for scissor action about a pivot joint (16) . The first member (12) includes a first handle grip (18) at a rear end and a first cutting element (20) having a first blade (26) at a front end. The second member (13) includes a second handle grip (19) at a rear end and a second cutting element (21) having a second blade (27) at a front end thereof . The cutting elements include a leg portion (40,41) positioned between an arm segment (30,31) on which the pivot joint is located and the blade. Each cutting element also has a gap (G) in the blade portion. The leg portions and the gap enable the cutting elements, when opened, to fit over a package lip of a blister-type package so that the package opener can cut around the interior perimeter of the package lip to open the package. The multi-function package opener may also have a miniature utility knife blade (50) and at least one screwdriver (60).
Claims (14)
1. ~A multi-function package opener comprising first and second opposed elongate members joined together for scissor action about a pivot joint, the first member comprising a first handle grip at a rear end and a first cutting element having a first blade with a cutting edge at a front end thereof and a first arm segment intermediate the handle grip and blade, and the second member comprising a second handle grip at a rear end and a second cutting element having a second blade with a cutting edge at a front end thereof and a second arm segment intermediate the handle grip and blade, the first and second arm segments being joined by a connector to form the pivot joint, wherein the first and second blades are offset from a plane passing through the first and second handle grips and the first and second cutting elements are shaped so as to form a gap G
between the cutting edges and the arm segments.
between the cutting edges and the arm segments.
2. ~The multi-function package opener according to claim 1 wherein each of the cutting elements includes a leg portion positioned between the arm segment and the blade, wherein the leg portion extends from the arm segment at an angle .gamma. of between 75 and 105 degrees to form the offset.
3. ~The multi-function package opener according to claim 2 wherein the offset formed by the leg portions has a height H between about 10 mm and about mm.
4. ~The multi-function package opener according to claim 3 wherein each of the leg portions is orthogonal with the arm segment.
5. ~The multi-function package opener according to claim 1 wherein the cutting elements pivot open to an angle a of between 40 degrees and 60 degrees between the cutting edges.
6. ~The multi-function package opener according to claim 1 wherein each blade portion extends at an incline angle between 55 degrees and 85 degrees from its respective leg portion.
7. ~The multi-function package opener according to claim 1 wherein each of the cutting blades forms a neck that transitions into its respective leg portion such that the cutting blade is narrower at its neck than at a location adjacent the cutting edge to form the gap G.
8. ~The multi-function package opener according to claim 7 wherein a width W of gap G is between about 5 mm and about 25 mm
9. ~The multi-function package opener according to claim 8 wlierein the gap G and has a length L defined as the distance from the cutting edge to the neck in the cutting blade, wherein the length L is between 5 mm and 25 mm.
10. ~The multi-function package opener according to claim 1 further comprising a utility knife blade.
